Terra MSR512 multiswitch has 4 x LNB inputs from a quatro lnb and 1 x terrestrial input feeding 12 completely independent outputs. The device has been designed for distributing satellite signals to a number of users (SMATV systems). It is compatible with all satellite platforms.
An important advantage of MSR-5XX multiswitches is diversification of signal levels at different groups of outputs. It allows to compensate the differences in attenuation of various lengths of cables that have to be used in the installation - we can get similar levels in all outlets. Additionally, the multiswitches compensate cable characteristics (provide higher levels for higher frequencies).
The following voltages occur at inputs of the multiswitch:
- 18 V DC at H, Lo and H, Hi
- 14 V DC at V, Lo and V, Hi
- 12 V DC at terrestrial signal input, suitable for powering an antenna preamplifier
The device is powered with 220-240V AC power network. All obligatory precautions for working with dangerous live voltages should be obeyed.
Unused inputs of multiswitches have to be closed with terminal resistors with blocking capacitors
